The second opening has a tab which extends from an edge thereof partially into the first opening. A knife is attached to the tab and supports a blade outwardly of the first plate and thus outwardly of the flywheel. A system is provided for providing water mist onto wood product only as it is being fed down the in-feed bin.

Abstract: A wood chipper, a flywheel therefor, and a process of making the flywheel. A plurality of plates are laser cut to each have a thickness up to about ? inch, including laser cutting a plurality of apertures in each of the plates and laser cutting a central opening in each of the plates for receiving a shaft for effecting rotation of the flywheel. The plurality of plates are laminated together by inserting fasteners in corresponding ones of the apertures in the plates. At least one knife is attached to the laminated plates for cutting wood material to form chips of the wood material as the flywheel is rotated.

Abstract: A wood chipper comprising a chamber in which wood is chipped, at least one roller for feeding of the wood into the chamber, and an hydraulic motor. Hydraulic lines flow connect a hydrostatic pump to the hydraulic motor for effecting rotation of the at least one roller for driving the at least one roller. A member on the wood chipper has splined projections for engaging splined projections on a member on the tractor to effect rotation by the member on the tractor of the member on the wood chipper in order for the wood chipper to receive mechanical power from a power take-off of the tractor for operation of the hydrostatic pump.

Abstract: A sawmill comprising first and second clamp members for clampingly engaging opposite sides of a log or log cant. A trolley includes the second clamp member. For moving the trolley cross-wise of the sawmill base, a threaded rotatable rod, to which a handle is attached, extends cross-wise of the base. The trolley includes a pair of walls which have a pair of aligned vertically oblong apertures respectively for receiving the rod. A half nut is fixedly attached to a bottom of one of the apertures and has threads which mate with threads on the rod so that the rod can threadedly engage the half nut.

Abstract: A wood chipper comprising a chamber in which wood is chipped, and a pair of rollers for feeding of the wood into the chamber. One of the rollers is a smooth roller and may or may not be an idle roller, and an other of the rollers is driven and has cutting elements thereon. One or more pressurized gas springs are attached to the rollers to apply a predetermined pressure to the rollers to cause the cutting elements to bite into the wood fed between the rollers. The cutting elements are blades each of which is un-notched in a direction radially of the other roller and each of which extends over substantially the entire length of the other roller.

Abstract: A method of making an in-feed roller for a wood chipper. The roller has seven, eight, or nine perimetric planar sides. It is made by providing a pair of end plates having a plurality of perimetric edges equal to the number of sides and a plurality of other plates equal to the number of sides. Each of the other plates has a first portion for extending between respective edges of the end plates and a second portion extending radially outwardly of the roller and terminating in a cutting blade. A junction or junction portion is defined between the first and second portions. Each of the end plate edges is provided with at least one first tab extending therefrom. The first portion of each of the other plates is provided with at least one first slot in each of ends thereof. Each junction is provided with at least one second slot therein.

Abstract: A portable sawmill which has an elongate central portion, at least one hinged foldable extension portion, laminated rails, detachable axle/wheel combinations, a tow bar, and adjustable legs. Spacers are received between each rail and the respective support structure for both the central portion and the extension portion, including one spacer a first portion of which is disposed between and attached to each rail and support structure of one of the central portion and the extension portion and a second portion of which is slidingly receivable between each rail and support structure of the other of the central portion and the extension portion as the extension is unfolded for use. A pull cable, when an actuation lever is engaged, effects pivotal movement of a cam to which another pull cable is attached for actuating the engine throttle for cutting wood. At least one other pull cable or other actuation member is attached to the cam to actuate at least one other device upon the actuation of the throttle.

Abstract: A portable sawmill has an elongate central portion, at least one hinged foldable extension portion, laminated rails, and a tow bar. An elongate tubular axle retaining member is mounted to the base. A pair of torsion axles, to which wheels and tires are attached, are received telescopically in opposite ends respectively of the axle retaining member and detachably attached thereto. A plurality of legs are attached to the base. The legs are height-adjustable to raise the base to a height such that the tires are raised above the ground so that the axles with the attached wheels may be removed.

Abstract: An in-feed roller for a wood chipper and a process of making thereof. The roller has seven, eight, or nine perimetric planar sides. It is made by providing a plurality of curved plates equal to the number of sides and a pair of end plates having a plurality of perimetric edges equal to the number of sides. Each curved plate has a side portion for extending between respective edges of the end plates, a knife portion, and a junction portion at the junction of the side portion and the knife portion. First tab and slot connections attach the side portions of the curved plates to the edges of the end plates respectively. Second tab and slot connections attach the terminal edges of the side portions of the curved plates to the junction portions of adjacent curved plates respectively.
